My invention has to do more especially with the cutting olf and deliveryof cut off lengths of wires from the machine, and, therefore, only abrief description of the machine in general and as shown in the drawingsherein Will be given, such machine comJ prising a bed 10 supporting aframe 11 upon the latter of which driving and operating mechanism issupported, this mechanism being of any ordinary type and constructionand which may include a motor 12 for driving such mechanism with feedrolls 13 and breaker rolls 14 for supplying wire to a flier orstraightening arbor 15.

The flier 15 is supported between bearings 16v-17 and a burnisher 18 islocated between the bearing 17 and a pair of feed rolls 19. Thisburnisher is not illustrated in detail herein but forms the subjectmatter of a se arate application'led by me concurrent y herewith and,therefore, no claims to the de tails of the construction are madeherein.

. My invention comprises a mechanism for cutting the Wire into definitelengths as it passes from the burnisher and the feed rolls 19, thismechanism being caused to travel by and With the wire as the latter ismoved.

This cutting mechanism comprises a supporting sleeve 20 secured Withinand projecting from the side of albracket 21 attached to the end of theframe 11, a carrier sleeve 22 belng mounted upon the sleeve 20 andmovable lengthwise thereon, one end of this sleeve 22 being slidablysupported in a side of said bracket opposite the end of t-he supportingsleeve 20. A retracting spring 23 is secured within the sleeves 20 and22 and at opposite ends of each, so that when the sleeve 22 is moved jin a manner to be hereinafter described it will, when released, be movedto its normal position by means of the spring.

A cutter frame is carried by the sleeve 22 and comprises a die carryingarm 24, a supporting arm 25 and a cutting arm 26. The arms 24 and 25 aresecured to the sleeve 22 in a manner to prevent movement of said armslengthwise of the sleeve, but to permit said sleeve to rotate withinsaid arms, and the cutting arm 26 is secured to said sleeve that formsan immediate support for said arm and that is rotatable upon the sleeve20.

The arms 24 and 25 are provided with actuating rollers 27-28 rotatablymounted on studs at the ends of the arms and in engagement with a camsleeve 29 on a shaft 30 rotatably. mounted in one of the sides of thebracket 21 hereinbefore mentioned and a bearing in a bracket 31 securedto the frame 11, and as shown in Figure 1 of the drawings. The shaft 30is driven as by means of intermeshing pinions and gears from a shaft 32connected by a train of gearing 33 with the motor 12, and as shown inFigures 3 and 4 'of the drawings, said shaft also being connected byintermeshing gears to drive the breaker rolls 14 and feed rolls 19, in amanner that will be readily understood without further illustration anddescription herein. The cutting arm 26 also has a roller 34 in contactwith a cutter operating cam 35 secured to the sleeve 29. f

In the operation of this cutting mechanism a wire 36 is fed through thestraightening arbor 15 and burnisher 18 by means of the feed rollshereinbefore described, and

Cal

through ya hole in a cutting die in the arm 24, and thence into areceiver 37. This receiver 37 comprises a bar with a roove in its undersurface into which the wire passes and within which itengages a tripblock 38 connected by a rod 39 with a clutch actuating lever 40rotatably mounted on a wire receiving frame, to be hereinafterdescribed. The lever 40 comprises an arm 41 having a connection 42 witha clutch actuator bar 43 appurtenant to a one revolution clutch 44mounted on the shaft 30, and as shown in Figure 1 of the drawings.

This one revolution clutch may be of any ordinary construction wellknown to. those skilled in the art and in the operation of which, whenthe bar 43 is actuated will make one com lete rotation and then stop.When the bar 1s actuated by a length of wire passing along the receiver,as herein just described, the operation of the clutch will Set the shaft30 in motion thereby rotating the sleeve 29 and actuating the cam 35 toswing the arm 26 and the sleeve 22 on the supporting sleeve 20. As soonas the cutting device on the arm 26 encounters the wire the latter willmove the sleeve 22 together with the arms 24-25-26, the cutting devicethus moving simultaneously with the wire to sever the end thereof. Thecam 35 is very short as shown in Fig. 6 and the action of the arm 26 is,therefore, comparatively' quick. Consequently, as soon as the end of thewire is severed the arm 26 reti-acts and the spring 23 returns thesleeve 22 and said arms to their normal position, and as shown in Figurel.

It will be noted that the arms 24-25-26 are partly supported by thesleeve 22 on the sleeve 20, and in order to prevent cramping action asforce is applied to the cutter to move it with the wire the. rollers27-28-34 are so inclined on the sleeve 29 that rotation of said sleevewill tend to move these ends of said arms in the same direction as thatin which the sleeve 22 is moving, and this construction enables thecutting apparatus to be su ported on a single bearing.

{re supports 45 in the shape of fingers are secured to a rocking bar 46mounted on a receiving frame including supports 47. These fingersunderlie the groove in the receiver 37 hereinbefore referred to and thewire in said groove` rests upon these fingers. The bar 46 has a baractuating arm 48 connected by a rod 49 with a wire releasing lever 50pivotally mounted on the bracket 2l and having a roller 5l engaging acam surface 52 on the sleeve 29, and as shown in Figures 5 and 6 of thedrawings.

In the operation of the wire releasing mechanism just described, whenthe cam sleeve 29 has been set in motion by the operation of the clutch44 as hereinbrtore referred to, the releasing lever 50 will be operatedto withdrawthe wire supports or fingers 45 and permit the wire to dropon to wire rests 53 where they are retained by jaws 5 4. The cam 52 isso positioned that this release of the wire will take place just beforethe arm of the lever 26 is operated to sever the next succeeding lengthof wire.

The clutch actuator bar 43 has a latch 55 spring pressed to enfrage oneend thereof with a clutch trip 56Ll1aving a stop arm 57 adapted to beinterposed in the path of movement of a nose, 58 of the clutch 44hereinbefore referred to and of ordinary con struction, and which willbe set into clutching action when the arm 57 is moved from engagementwith the nose 58 by operation of ithe bar 43 in a manner that will bereadily tunderstood, springs 59-60 returning the parts to their normalpositions as soon as a wire has been severed as hereinbefore described,and the stop 57 being thusin position to engage the nose 58 and stopoperation of the clutch at the end of each complete rotation thereof.

As hereinbefore noted the cutter mechanism is supported upon a singlebearing, this being the sleeve 20 upon which it has an easy sliding fit,the opposite ends of the several levers with their diagonally arrangedrollers aiding in the movement of the structure along said sleeve. Thearms 24 and 25 are rigidly connected at their ends opposite thesupporting rollers by a tie 61.

The wire supporting fingers 45 are held normally underneath the groovein the bar or receiver 37 by means of a spring 62 in a case 63 pressingagainst a rod 64 pivotally connected with the wire support 45, and asshown in Figure l0 of the drawings.

rThe trip block 38 has guide plates 65 slidably fitting grooves in thereceiver 37, and as shown in Figure 10 and by means of which an easysliding movement of said trip block is provided for.

A treadle 66 is attached near each end of a wire discharge shaft 67rotatably mounted in the frame supports 47, said treadles beingconnected by bars 68 with each of the jaws 54, whereby upon pressure asof a foot upon either treadle said jaws will be swung downwardly topermit wires collected on the rests 53 to slide therefrom and bedischarged from the machine.

In order to provide for a quick discharge of the wires from the jaws 54the bar 68 is pivotally attached at its lower end to a toggle lever 69loosely mounted on the shaft 67 and underlying the treadle 66, and asshown in Figure 2 of the drawings. When the jaws 54 are in theirreceiving positions, as shown in Figure 3, the pivot connecting the bar68 and toggle 69 will be at one side of a line extending between theaxes of the shaft 67 and the pivot connecting the bar 68 with the jaws54, in which position the toggle rests against sin a tube ormin a partof the wire dis char e frame, so t at pressure upon lthe )aws 54 willtend to force the toggle into contact with said tube. Pressure of thetreadle 66 will move said pivot to the opposite side of said line,whereupon there beln no further resistance to movement of the ]aws 54they will swing quickly downwardly b reason of the weight of the wires,thereby ischargmg the latter. It is here remarked that the jaws 54 aresecured to a rock shaft 71 rotatably mounted in the frame supports 47.
